Summary
Convert any angle from gradians (grad/gon) to radians using the formula radians = gradians × π/200, with a step-by-step breakdown and common angle reference table.
How it works
- Enter an angle in gradians (grad or gon) in the input field.
- The converter applies the formula: radians = gradians × (π / 200).
- The result is displayed as a decimal and as a multiple of π.
- A step-by-step breakdown shows each stage of the calculation.
- Click any row in the reference table to load that angle into the converter.
Use cases
- Converting gradian angles from surveying equipment to radians for computation.
- Checking angle equivalents when working in civil engineering or geodesy.
- Understanding the relationship between the gradian and radian systems.
- Verifying manual conversions of common right-angle multiples.
- Teaching or learning the gradian unit used in European surveying.
- Preparing gradian measurements for use in trigonometric functions.
